Torvalds Slams NVIDIA's Linux Support

Linus Torvalds received the Millennium prize last week for his work on Linux operating system. He was already in Finland, so Aalto University arranged a talk session with him (video). During the Q&A, a person asks why NVIDIA does not play well with Linux. Torvalds explained shortly that NVIDIA has been one of the worst companies to work with Linux project — which makes it even worse that NVIDIA ships a high number of chips for Android devices (which use Linux inside). Torvalds even summarized that ('Nvidia, f*** you!') in a playful manner. What has been your experience on NVIDIA drivers with Linux?
